[AArch64] Remove redundant fmovs when bitcasting from ext/trunc of bitcast (#175983 )

The following can be used to reinterpret & extend a float, returning the
result as a double with the upper bits cleared:
  return bit_cast<double>((uint64_t)bit_cast<uint32_t>(x))

this currently results in two fmovs being generated, i.e.
  fmov    w8, s0
  fmov    d0, x8
  ret

This patch adds a pattern to improve this by using a single `fmov s0, s0`
instead, and also for the case where the integer value is truncated.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.
